Well her mom remarried/had another partner- maybe with her half siblings and the stepdad there wasn’t any room for her? Or maybe the stepdad had some issue with it? She seems closer to her mom (just mentions in the vlogs) which not like WEIRD but “something” if she spent more time growing up in another house. She hadn’t mentioned her dad in a long time in the vlogs. He seemed very nice and cheery, I wonder if he just didn’t want to be filmed anymore.
